In particular, the application of ASME B31.3 requires compliance with the Inspector
Cadweld Exothermic Welded C.P. Cable Connections by Erico 2.1. CA15 for steel pipe. 2.2. CA32XF19 for cast, wrought and ductile iron pipe. 3. These restrictions allow for the welding of #4 AWG and smaller wire to steel pipe using Cadweld Cathodic Type CAHA connections and #6 AWG and smaller to cast, wrought, and ductile iron using Type CAHB connections.
Consulting - Specifying Engineer Selecting pipe and Sep 17, 2018 · Over the past decade, mechanically coupled thinner-wall (schedule 10 304 stainless steel, or SS) pipe has become more common for 2.5-in. and larger domestic-water systems. It offers high corrosion resistance and a lower installation cost as compared with schedule 40 galvanized steel, or Type L copper pipe.
Use internally galvanized, stainless steel, or similar corrosion-resistant pipe in all new dry-pipe, pre-action, refrigerated-area, deluge, and exposure-protection sprinkler systems. Do not use galvanized pipe in areas where the ambient temperature could exceed 130°F (54°C) unless the pipe is specifically FM Approved for use in such conditions.
Design of Cathodic Protection for Duplex Stainless Steel Duplex stainless steel pipeline with Al anode,48 dia. Duplex stainless steel pipeline with Zn anode,24 dia. Results. From the calculations, it can be inferred that the Duplex stainless steel requires less amount of anodic material. A graph (Fig. 4) is shown for Mass of the anode (kg) vs current output(A).
JFE Steel Corporation Pipes and Tubes R&D & Technical No.12 Special Issue on Steel Pipes and Tubes and Stainless Steel Strain Capacity of High-Strength Line Pipes:2008.10:No.12 Special Issue on Steel Pipes and Tubes and Stainless Steel Development of API X80 Grade Electric Resistance Welding Line Pipe with Excellent Low Temperature Toughness:2008.10
Electrolysis is an overused and misused term when applied to copper tube. True elec-trolysis, or electrolytic corrosion, as it is more properly designated with regard to piping, is caused by an imposed (external) stray DC current and virtually ceased to occur with the disappearance of the trolley-car that was powered by high amperage DC current.
Protective Coatings LINE-XLINE-X Protects. LINE-X ® has long been known for tough, nearly indestructible spray-on bedliners. What many people dont know is that because LINE-X is a spray-on protective coating, it can be applied to almost anything. Thats how weve built a reputation for durability and long-lasting protection that extends far beyond our bedliners.

stainless steel pipe unit assembly is required. The pipe shall terminate a maximum of 18 inches from the exterior wall and a minimum of 6 inches above the finished floor. A minimum of 2 inches clearance (annular space) shall be provided where the pipe passes through the floor or wall.
What is Passivation? How Does Stainless Passivation Work?Stainless steel derives its corrosion-resistant properties from the chromium content. Chromium, when exposed to oxygen (air), forms a thin film of chromium oxide that covers the stainless steel surface and protects the underlying iron from rusting. The purpose of passivation is to augment and optimize formation of the chromium oxide layer.
